Web2 days ago · DC Analysis: NOTE: For DC analysis capacitors are open circuited, so DC voltage and current values (i. e. V B E, V C E, I B and I C) values are same for with and without C E. If the transistor is made up of Silicon (Si) Base-to-Emitter voltage V B E = 0.7 V. Thevenin's Equivalent Values for the given voltage divider bias circuit DC circuit. WebThe DC load line discussed previously, analyzes the variation of collector currents and voltages, when no AC voltage is applied. Whereas the AC load line gives the peak-to-peak voltage, or the maximum possible output swing for a given amplifier. We shall consider an AC equivalent circuit of a CE amplifier for our understanding.
